SOUNDING TACKLE.

Specification of Letters Patent.

Patented Oct. 26, 1909.

Application filed. August 1, 1908. Serial No. 446,389.

T 0 all whom "it may concern:

Be it known that we, OSCAR GU'r'r, oflicer of the Imperial German Navy, German su ject, residing at No. 1 Am Markt, Geestemiinde, Germany, and FRIEDRICH HERMANN CARL HEYN, gentleman, German subject, residing at No. 1 L Averhoffstrasse, Germany, have invented new and useful Improvements in Sounding-Tackle, of which the following is a specification.

()ur invention relates to a sounding apparatus, presenting a hose-pipe adapted to be let down into the water and whose nonsubmerged end is provided with a pressuregage, in order that, by means of the airpressure in the hose, depending upon the of the Water may be read the gage.

The characteristic feature of the invention consists in the provision of a special water inlet tube for the air-reservoir, which is connected with the lower end of the hose. This tube is furnished at its bottom end in well-known manner with a lip-valve,

the hose is greater than the water pressure. This valved water inlet tube thus prevents air from escaping from the air reservoir on the tackle being cast, so that there is always a guarantee for the accuracy of the measurement. The provision of the lip-valve also prevents the entrance of dirt into the airreservoir. It further insures perfect emptying of the air-reservoir on each occasion of the apparatus being drawn up out of the water, as the water can flow out unobstructed through the lip-valve.

Our invention is illustrated in the accompanying drawing, which shows certain constructional forms by way of example.

Figure 1 is a side elevation of the air reservoir attached to the lower end of the hose. Fig. 2 is a vertical section thereof. Fig. 3 is a view of the entire sounding tackle, the central portion of the hose-pipe only being omitted. Fig. I is a perspective view showing the employment of the air reservoir in conjunction with a so-called waterkite. Fig. 5 is an elevation of the air reservoir shown in Fig. 4:, and Fig. 6 is a like view, the reservoir having been turned through 90 degrees.

To the top end of the hose-pipe a there is Hamburg,

hose-pipe a and a rubber lip-valve 0 flat strips of rubber joined together at two part which WlllCll only opens outwardly when the pressure of the air confined in the air-reservoir and in' 1 to the'lip-valve 0 secured a pressure-gage b, and to the bottom end an air-reservoir 0.

In the construction shown in Figs. 1-3, the air-reservoir consists of a preferably cylindrical casing 0, whose bottom part is loaded, for instance by pouring in molten lead d or the like. The top of the casing, which may advantageously be conically tapered, accommodates a tube f, having a threaded end 9, to which there is screwed the I nipple h for connection of the hose-pipe a.

Inside the latter is a short tubular stiffener m, to which the hose a is bound by a ring 70. This latter is secured by means of wires j to eyes i screwed into the nipple h. In this manner the strain is taken off the end of the disconnection of the latter from the air-reservoir thus prevented. At the side of the air-reservoir 0 there is a tube a, the bottom end of which is furnished with which consists of two edges and formed at the one end to a socket is adapted to fit on to the end of the tube n. This lip valve 0 will be closed so long as the externalpressure is greater than the internal pressure but when the internal pressure exceeds the external pressure then the parts of the two strips of rubber which are not joined together will be forced apart and a passage will be formed therebetween. The tube a has a branch 19, entering the interior of the air-reservolr c, and

its top end 1" is flared and downwardly turned to facilitate entrance of water.

WVhen the loaded vessel 0 is cast, the hydrostatic pressure of the water which enters the tube at (and which cannot escape owing being kept closed by the pressure of the water outside) causes compression of the air confined in the reservoir 0 and hose a. This pressure will naturally increase the deeper the air-reservoir is let down into the water. This air-pressure is transmitted to the pressure-gage b, which enables the air-pressure and thus the depth of the water to be read off directly. On

drawing up the apparatus from the water,

the lip-valve 0 will open, so that the volume of water which has entered the reservoir 0 flows out again. To enable complete emptying of the reservoir, the branch 29 of the tube a should be located immediately adjacent to the bottom of the vessel constituted by the weight d.

'tube 72 causes compression of the fined 1n the'alr-reservoir c and in the hose a.

interior of the air reservoir, although absolute draining of the reservoir is insured onits withdrawal from the water, so that the apparatus is always ready for re-use.

Figs. 46 illustrate the employment of the new soundingtackle in conjunction with a so-called water-kite whereby a very practical'drag sounding-apparatus is constituted. The water-kite S consists of a boxshaped body open at both ends and having lateral apertures. Its lower part .9 is preferably constructed of iron and its upper part 8 ofwood. The part 8" is loaded by weights 8 This composite body S is attached by ropes t t to the drag-line 6 in such manner that the water-kite assumes the inclined position'shown' in Fig. 4, in which the current of-water acts against the inner and outer body-walls presented to it. current of water always tends to force the kite down.

The air-reservoir 0 (Figs. 5'and 6), provided with the water inlet tube a, is secured to the water-kite in any suitable manner. The base-pipe a conducting to the pressuregage (not shown in these figures) is attached to the air-reservoir by meansof a screwconnection u. To enable better connection of" the reservoir c to the water-kite S, the

former is'furnished at top and bottom with notches o '0 in whichthere engage the upright diagonal bars a? a" of the kite. y is the so+callcd auxiliary-line of the kite.

The manner (if-operation of this apparatus is the same as that of the tackle-shown in Fig. 18. 'On the'apparatus being cast, the water-current will drive it down, the depth depending upon the length of the dragline F. The pressure of the water entering the air con- This ;pressure will naturally increase the deeper the air reservoir is let down into the water. This air-pressure is transmitted to the pressuregage,-so that the depth of the water can" be read off directly. On drawing "up the apparatus out of the water the lipvalve- 0 twill open,-so that the volume of "waterwhich has entered the reservoir c flows out again.
